1. Sketch the graph of a continuous function so that limx-->infinity f(x) does not exist. 2. Sketch the graph of a function so that limx-->2 f(x) does not exist. 3. Evaluate the limit limx-->3 (x^2-x-6)/(x-3) 4. For each arc lenth sketch the arc on the unit circle, find the reference number, and find the terminal point. 4.1 --> Arc length: t= -5pi/3 4.2 --> Arc length: t= 11pi/4 5. Suppose t is an arc length on the unit circle and (a,b) the terminal point of t. Find the value of each trig function. 5.1--> sin(-t) 5.2--> cos (t+pi/2)
